Sebek Zigvolt

Sebek is a tall boy with fair skin. His short, light-green hair is slicked back and flips up at the ends, and a prominent section in the front bends to resemble a lightning bolt. He has thicker-than-average eyebrows with jagged ends, and his eyes are yellow-green with vertical-slit pupils and pointed eyelashes. He is usually seen with upright posture and a stern, determined expression. When his mouth is open, sharp fangs are visible. Sebek’s uniform is similar to the rest of the Diasomnia students. Sebek also wears green eyeliner while in his dorm uniform. The uniform consists of a black all-weather coat with neon green and silver accents, black combat suspenders and belts, jodhpur pants, a small garrison cap, black gloves, and heeled knee-high boots.

The all-weather coat has asymmetrically colored lapels, with one black and one neon green. Both lapels have silver straps and buttons on them. Two silver zippers go down the center of the coat, lined with neon green stripes. The coat reaches below the waist in length, and the sleeves are folded up to reveal a neon green underlining with silver trim. Sebek wears a white collared shirt and black tie underneath his coat.

Over the coat and above the waist is a set of black belts with silver buckles. The lowest belt hangs at an angle, and connects to several silver spools of thread on his left hip. Between the belt and spools is a silver ornament, shaped like a spinning wheel. On the other side of the belt is a holster for a magic pen. The black combat suspenders worn above the belts have silver buttons and a unique cuff around the right arm that resembles a dragon’s wing.

The jodhpur pants are black with neon green stripes going down the outer seams, and the knee-high boots are black with neon green soles. The garrison cap is black with neon green trim, and the sides fold up to resemble curved horns. Sebek is loud, hot-blooded, and prideful. Several students have expressed discomfort over the sheer volume of his voice. Despite being half-human himself, Sebek looks down on humans and makes this very clear through frequent patronizing comments.

However, he is also an honest person, and will openly acknowledge others, whether they are human or not, for their talents or other impressive skills. He is blunt and not afraid to express his thoughts. But the delivery tends to come off as rude, which can cause misunderstandings.

Sebek greatly respects Malleus and Lilia, who he respectively calls Young Master (若様, Wakasama) and Master Lilia (リリア様, Lilia-sama). He becomes much politer and meeker when addressing them. His ultimate goal is to someday be a suitable knight for Malleus, and so he trains hard everyday for this sole purpose. Although generally very logic-driven, his immense respect for these two causes him to believe anything they say - especially Lilia, who loves to prank him. Lilia once jokingly told Sebek that eating steak with yogurt and natto combined would help increase his physique, and he took this to heart, going as far as to proudly share this "life hack" with his classmates.[1]

Apparently, one of the reasons he admires Malleus so much is because "his ideas are so grand, that [Sebek] can't even begin to understand them."
